ABBA F. CLARK, OF BOSTON, MASSACHUSETTS.

CAR-STARTER.

SPECIFICATION forming part of Letters Patent No. 274,463, dated March27, 1883. Application filed September 16, 1882. (No model.)

To all whom it may concern:

Be it known that I, AREA F. CLARK, of Boston, in the county of Suii'olk,of the State of.

Massachusetts, have invented a new and useful Improvement in Mechanismfor Stopping and Starting Street-Railway Cars; and I do hereby declarethe same to be described in the with my invention, the nature of whichis defined, in the claims hereinafter presented.

With my improvement the power of starting the car is not generated bythe momentum of the car in the process of stopping it, as is the casewith various other mechanical carstarters, but is derived from thedriver or brakeman in setting up the brakes or drawing them tothewheels; and to thiscnd thereis combined with the actuating cranked shaftof the brake-operative mechanism a mechanism for starting the car whileor after such cranked shaft may have been set free, so as to allow thebrakes to be moved away from the wheels.

In the drawings, the car platform or body is shown at A and the axles ofits four wheels on at M M. The actuating cranked shaft of the brakes bis represented at V, it having fixed to it a rope or chain, B, extendingfrom it and fastened to one arm of a lever, X, such lever being arrangedat the middle of and underneath the car platform or body. From the armsof this lever, ropes or chains d d extend to the brake-connection bars e6. By turning the shaft V so as to wind the chain B thereon, the brakeswill be set up to the wheels. There is fixed upon the shaft Vv a pulley,G, to whose periphery a chain or rope, f, is fastened, such chain orrope being also fastened to the longer arm of a bent lever, F, arrangedas represented. To the arms of this lever ropes I and I are fixed andextended around sheaves s s in two carriers, E and J, arranged as shown,such ropes being fastened to two draw-pawls, G and L, each of which ishinged to one of two bow-springs, H and N, arranged underneath thecar-body and supported near their ends in staples P or other properdevices. These draw-pawls extend through stationary staples g g anddirectly over I two ratchet-wheels, D D, fixed upon the axles W is ahanger for supporting the lever X. On turning the shaft V to set up thebrakes the chain or rope f will be wound upon the pulley G, and willturn the lever F, whereby its ropes I and 1 will be caused to draw thepawls forward over and into engagement with the ratchet-wheels, thesprings with which the said pawls are connected being in the meantimecontracted, in order that when the shaft V may be set free to revolvebackward to relieve the wheels from the brakes the power thus generatedin the springs may cause them to expand and draw the pawls against theratchet-wheels in order to cause them to revolve the axles, and therebystart or aid in starting the car forward. Each of the drawpawls,formedas represented in Fig. 4, will at a proper time, in being drawn backwardin its supporting-staple 9, rise or be caused to rise out of engagementwith its ratchet-wheel, such being to enable it to revolve withoutcontact with the pawl while the car may be running on the track. Werethe pawls to rest on the ratchet-wheels while the car may be running,disagreeable noise or clatter would result.

I do not claim the brake-operative mechanism as hereinbefore described.

\Vhat I do claim is- 1. The combination, with the brake-operativemechanism actuated, as specified, by its cranked shaft V, of mechanism,substantially as described, for starting the car, such consisting in thepulley G, chain or rope f, lever F, chains or ropes I I, draw-pawl's GL, bowsprings H N, and ratchet-wheels DD, all being arranged and adaptedsubstantially as set forth.

2. The car-starting mechanism or combination, substantially asdescribed, consisting of the pulley G, chain or ropef, lever F, chainsor ropes I I, draw-pawls U L, bow-springs H N, and ratchet-wheels I) 1),arranged and adapted essentially as set forth.

3. The combination of the staples g g with the draw-pawls (3 L, theratchet wheels D l), springs H N, chains or ropes I I, lever F, chain orrope f, and pulley G, applied to the cranked shaft V, all being arrangedand adapted substantially as shown and described.
